Solution for (4/x)=(x/8) equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

4/x = x/8 // - x/8

4/x-(x/8) = 0

4*x^-1-1/8*x^1 = 0

(4*x^0-1/8*x^2)/(x^1) = 0 // * x^2

x^1*(4*x^0-1/8*x^2) = 0

x^1

(-1/8)*x^2+4 = 0

(-1/8)*x^2+4 = 0

DELTA = 0^2-(4*4*(-1/8))

DELTA = 2

DELTA > 0

x = (2^(1/2)+0)/(2*(-1/8)) or x = (0-2^(1/2))/(2*(-1/8))

x = -4*2^(1/2) or x = 4*2^(1/2)

x in { -4*2^(1/2), 4*2^(1/2)} 

x in { -4*2^(1/2), 4*2^(1/2) }
